GONG-ACTUATING MECHANISM FOR ELECTRIC CARS.

' Application filed June 24, 1912.

Specification of Letters Patent.

I '0 all whom it may concern Be it known that. l, ROBER'IF ALLEN Hnr imeir, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented a new anu useful Gongi ictuating lvlechanism for lllleetrie Cars, of which the following is a specification.

The present invention relates to improvements in gong actuating mechanism for electric cars, the primary object of the invention being the provision of a gong in which the electrical connections LO actuate the same are disposed in operable relation to the controller box and controller handle of an electric car, the controller handle being provided with a novel form of normally open switch, whereby the niotorman may at any desired time, regardless of the position of the controller and whether or not the car is in motion, actuate it to close the gong circult to ring the gong.

A further object 01 the present invention is the provision of a novel form of switch mechanism disposed within the controller handle and bodily removable therewith, the same being provided with two contacts which normally e upon two concentric metal rings carried by an insulation body upon the upper surface of the controller box, the controllerhandle leir further provided with a novel form of soil h actuating mechanism, so i l at the gong circuit may be energized at will.

A. still further object of the present invention is the provision of a Contact carrying mechanism detachahl i connected to the under side of a controller handle of an electric car, and bodily removzole therewith, the same lazing: readily attached without the new at oi altering the usual construction oi? the handle thus permitting theemployment of the handles now in use and not necessitating the discarding of the same as the usual practice in applying devices of this kind.

lVith the fdregoing and other objects in view which will appear as the description. proceeds, the invention resides in the combination and arrangemencof parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodimentof the invention herein disclosed can he made within the scope of what is claimed without departing from the spirit of the invention.

In the clrawings--lfigure 1 is a top plan view of the complete apparatus with the gong and electrical circuit in diagram. Fig. 2 is a side elevation of thecomplete mechanism, with a section on line 2-2 taken through the controller.

Referrin'g'to the drawings, the numeral 1 designates the top of the controller box which has mounted thereon the insulation ring 2 which is disposed concentrically of the shaft of the controller arm, and has mounted therein so as to be insulated one from another, the two concentric metal rings 3 and 4, which constitute the two stationary contact plates'of the gong circuit. The controller arm 5 mounted as usual, the main portion of which is hollow and is actuated by the upstanding handle 6.

Disposed for slidable movement within the removable casing Cl attached to the underside of the controller arm 5 and normally held in contact with respect to the respective rings 3 and 4-, are the metal con tact pins 7 and 8 which are slidahly mounted within the bushings 9 of insulation carried by the casing of the controller arm 5. The springs 10 are disposed within the casing of the'controller arm 5 and are so mounted as to normally holdthe said contact pins 7 and 8 downwardly, as clearly shown in Fig. 2. Led from the eon'taetpin 8 is a conductor 11 which is also connected to the metal plate or spring contact 12 disposed upon the block 13.01 insulation within the casing adjacent to the handle 6 of the controller. A movable spring contact plate it, normally exerting a pressure out of contact with the metal contact plate 12, is mounted upon alolock 15 of insulation within the controller casing and has led therefrom a, conductor 16 which is conhected to the contact pin 7. I

In order to actuate the spring contact plate or switch 14- so as to cause the engagement thereof with the contact plate 12, a sleeve 17 is mounted concentrically of the handle 6 and has slidebly mounted therein a pin 18, whose lower end 19 is disposed to be projected into contact with the spring contactplate or switch 14 to depress the same and close acircuit, the knob 2d of that the spring contact pins 7- and 8 rev gardless of the position of the controller the switch actuating pin 18 forming in. reality a push button within the socket 21 formed in the upper end of the handle 6.

A conductor 22 is connected to and led arm 5 are in contact at all times with the metal contact rings 3 and 4 and'that as long asthe switch actuating pin 18 is in the position as shown in Fig. 2, the switches 12 and 14 are separated,but that at any point, the pin 18 may be depressed to. close the switch points 14 and 12 and thereby close the C11- cuit. to the gong 23 so that the gong may be energized with the controller arm 5 in any position, and consequently with the car moving or at a stand'stilh It will also be noted that the handle and casing G are bodily removable, so that the usual change may be made in using the controllerat either end of the car! Also it is evident that the present device may be readily attached to I apparatus I now in use.

What is claimed is: In a gong actuator, a controlling box having a stem, an audible alarm, a source of electrical energy and the combination with two insulated concentric rings disposed upon the controller box and concentrically 4 about the controller stem, of a circuit closing device including a controller handle for detachably engaging the stem, a casing detachably' connected to the under side of the controller handle and havinga, project- 4 ing portion above and parallel with the two concentric rings, a projection carried by and within the casing above and in spaced relation with the: projecting portion, the pro jecting portion and the incased' projection 5 being provided with two vertically parallel apertures, two metal contacts mounted in the apertures. of the parallel portions and disposed to ride upon the concentric rings, sleeves normally mounted in'the apertures of 5 theproJeetiOns within the casing and insulated therefrom, a spring mounted in each sleeve (for holding the contacts resiliently in ring engaging position, a conductor led from each of the sleeves throughout the length of 6 the handle, a stationary contact plate connected to one of the conductors, a spring contact plate connected to the other conductor: and normally held out of engagement'with the stationary contact, and a'push pin slid: 6

ablymounted in the gripping handle of the controllerand for causing the closure of the contacts at will. a

In testimony that I' claim the foregoing as my own, I have hereto aflixed my signa ture in the presence of two witnesses.
